A loud bang triggered a security lockdown at the White House on Saturday after a souvenir truck caught fire in a neighboring street, the Secret Service said.
According to the Secret Service, the security alert was issued just moments before US President Barack Obama and the first family was due to leave for Andrews Air Force Base.
The President and his family were about to board a helicopter from the South Lawn of White House.
Brian Leary, spokesperson for Secret Service, said that the security officials succeeded in containing the fire. According to Leary, the security officials also spotted a vehicle near the White House and following investigations they cleared it for any threat related to bombing.
According to the White House officials, Obama along with his family left the presidential mansion by motorcade instead of boarding a helicopter an hour later and boarded Air Force One at Andrews Air Force Base.
The Obama family is traveling to Selma, Alabama, for commemorating the 50th anniversary of a civil rights march.
The security officials said that they had to close several streets in the vicinity of the White House for a few hours. The streets were, however, reopened soon after noon. The tours at the White House were also disrupted due to the nearby fire, but everything resumed in late morning after the dog team gave clearance to the nearby vehicle.
The reports suggested the souvenir truck, which was was completely destroyed by the fire, belonged to a Korean family from Virginia.
